Any suggestion or advice is warmly appreciated. The first thing I'd check is to make sure you that you have /dev and /proc mounted inside the jail. You should have lines similar to this in your /etc/fstab: proc /var/chroot/sid-ia32/proc proc defaults 0 0 /dev /var/chroot/sid-ia32/dev none bind 0 0 (note that the "proc" line does NOT have a / before it) -- Alex Malinovich Support Free Software, delete your Windows partition TODAY!
